We recently completed replacement of our three skylights on a stone-coated metal roof, and I want to sincerely thank NSS for their excellent work. This was not an easy project, and several companies were not willing to take it on, which …

Awesome job replacing three skylights. Marvin and Jack were professional and competent with the install, and Ashlee made the process of selecting the correct skylights, as well as providing several options a breeze.

Haven't heard back from them???? As a former customer, they need to be more responsive! I only asked a simple question.....

After searching for more than 2 years for someone who could repair or replace a "lean-to" skylight originally installed by the builder, I finally found a reputable company that could do the work and has done similar requests. By this time, the skylight was more than 35 years old. It was part of a Pella Window installation. Pella went out of the skylight business about 20 years ago and would not work on either repairing or replacing the skylight. NSS Exteriors knew exactly what the problem was, when we explained it to them, came out to our townhouse and provided us a timely quote. Other skylight "specialists" wouldn't touch the project because of the fact the sky light sits in a box that requires drilling into the brickwork to install it. It was also situated on top of a fairly new Pella window which had been replaced several years before - Pella at that time told us they would not touch the skylight. There was a slight delay in getting the new skylight from the manufacturer due to COVID, but it was finally installed the week of Jan.10, 2021. The men worked well together, they were careful and respectful and were willing to listen to our concerns and make corrections where needed. Thank you for a job well-done!

Recently used NSS supplies and installer to remove current roof, and install a metal roof on my 100yr old small bungalow cottage in SW Michigan. Work is almost done as you can see from the pics. Have received so many compliments from the …

Old garage roof was two layers of worn out shingles. Installer worked tirelessly in hot and humid weather to removed old roof, replace bad roof boards, put down tar paper and install the metal roof. Once all the old was gone and the tar paper was laid down the actual product installation was relatively quick.

Thank You to you and your team for taking the dilapidated skylights at the Elston property and making them amazing! We so very much appreciate your artistry, organization, professionalism and true customer service. Again, Thank You.

I had them replace a skylight in my kitchen in the fall of 2018 and was ready to get a second one replaced in my bathroom. They are extremely responsive and professional. They coordinated with my roofer to be on site to not only install the new skylight but also monitor the work around the previously installed one to make sure nothing was damaged. I would definitely recommend them if you are looking to install or replace a skylight.

I had solar skylights installed to replace my old broken venting ones! Well worth the extra money!!! They installed them quickly, cleanly & expertly. 4 or 5 years later, the battery went dead on the remote & I was unable to do it myself. …

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 43 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 23, of which 14 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
